Well, perfect if you don’t mind losing your bottle of wine as soon as you go over the first bump you encounter. That does not look secure at all.

…or stopping suddenly. My eyes suggest the failure mode would be for it to slide forward on the top tube until the neck of the wine bottle hits the head tube, or for it just to slide out of the bracket on the bottle bottom until the bottle swings down and free of the strap on the bottle neck, smashes to the ground and then slashes up your rear tire.

Both of these could be easily remedied though.

Plain ol’ water bottle cages work just as well.

With no way of keeping the two ends from sliding apart you could easily lose your bottle.

Tip: this should be sold (or at least publicized) in italian university cities, e. g. Padova. The amount of people who ride a bike everywhere, combined with the amount of people who carry bottles of wine for friendly encounters at night, is reason enough for this solution to be widely accepted among the student community :D

The seller says this:
“The rack secures tightly to the frame so that the two parts do not separate. I’ve tried it with a bunch of different bottles and it’s nicely flexible.

The fittings and hardware are all brass.
It only fits a 1″ bike frame!”
